在编辑 UITableView 时是否可以隐藏“-”(删除)按钮

Here is my complete solution, without indentation (0left align) of the cell!

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}


- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewCellEditingStyleNone;
}


- (BOOL)tableView:(UITableView *)tableview shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath {
return NO;
}




- (BOOL)tableView:(UITableView *)tableview canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}

This stops indentation:

- (BOOL)tableView:(UITableView *)tableview shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath {
return NO;
}

I faced a similar problem where I wanted custom checkboxes to appear in Edit mode but not the '(-)' delete button.

Stefan's answer steered me in the correct direction.

I created a toggle button and added it as an editingAccessoryView to the Cell and wired it to a method.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {


....
// Configure the cell...


UIButton *checkBoxButton = [[UIButton alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 40.0f, 32.0f)];
[checkBoxButton setTitle:@"O" forState:UIControlStateNormal];
[checkBoxButton setTitle:@"√" forState:UIControlStateSelected];
[checkBoxButton addTarget:self action:@selector(checkBoxButtonPressed:) forControlEvents:UIControlEventTouchUpInside];


cell.editingAccessoryType = UITableViewCellAccessoryCheckmark;
cell.editingAccessoryView = checkBoxButton;


return cell;
}


- (void)checkBoxButtonPressed:(UIButton *)sender {
sender.selected = !sender.selected;
}

Implemented these delegate methods

- (BOOL)tableView:(UITableView *)tableview shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath {
return NO;
}


- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleNone;
}

Swift 5 equivalent to accepted answer with just the needed funcs:

extension YourViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, shouldIndentWhileEditingRowAt indexPath: IndexPath) -> Bool {
return false
}


func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCell.EditingStyle {
return .none
}
}

When you only want to hide the (-) dot while editing but you may want to keep the deleting functionality for the users you implement it like so in your UITableViewDelegate protocol conforming class

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
if (self.editing) return UITableViewCellEditingStyleNone;
return UITableViewCellEditingStyleDelete;
}
